A separate checkin might have been good. However at this point, a "cvs=20
admin -m" will probably be enough to fix things up. I agree we should note=
=20
this change, but I don't think it's so bad to include it.

The difference I see is who gets to set it. VXLOCK is set by vfs_subr.c;=20
it is owned by the FS-independent code. VFREEING, however, is set by the=20
FS-specific code.=20

The only thing I find missing is that there isn't any code which USES the=
=20
new flag. Did a checkin get missed?

Take care,

Bill
